Answer: The amperage needed to complete the electrolysis in the given time is 9.08 A
Explanation:
We are given:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Charge on 1 mole of electrons =
moles of calcium =
is required to deposit = 1 mole
Thus 1 mole is deposited by = 193000 C
2.49 moles will be deposited by =
To calculate the time required, we use the equation:
where,
I = current passed = ?
q = total charge =
t = time required = 14.7 hours =52920 s ( 1hour=3600s)
Putting values in above equation, we get:
Hence, the amperage needed to complete the electrolysis in the given time is 9.08 A
